Suspended chords pull the third out entirely, so they land somewhere between major and minor rather than picking a side. Sus2 fills the gap with a major second sitting close to the root, which gives it an open, slightly hollow color. It's a favorite way to add movement to a strummed or arpeggiated part without changing the underlying harmony.
